NEW EUDESMENOIC ACID METHYL ESTER FROM ARTEMISIA SELENGENSIS

The aerial parts of Artemisia selengensis yielded a new eudesmenoic acid methyl ester together with a known eudesmanolide. The structures were elucidated by spectroscopic methods. The relative stereochemistry of the title compound was further supported by the result of a successful single-crystal X-ray diffraction analysis.
